Embodiment Construction

[0029] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be practiced. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar units are denoted by the same reference numerals.

[0030] Such as figure 1 As shown, the existing display screen includes a heat dissipation film 10 and a display panel 20, and the heat dissipation film 10 generally includes a three-in-one structure of foam (Foam) 11, graphite 12 and copper foil 13, but the graphite 12 is a sheet structure, and the heat is mainly Conduction along the length direction of the graphite...

Abstract

The invention provides a display screen and an electronic device. The display screen comprises a display panel and a heat dissipating film, the heat dissipating film is arranged on the back face of the display panel, the heat dissipating film comprises a heat conducting layer, and the heat conducting layer comprises one or more of a carbon nanowall, a metal nanowall and an oxide nanowall. According to the display screen and the electronic device, the heat dissipating effect can be improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to a display screen and an electronic device. [0003] 【Background technique】 [0004] Flexible organic light-emitting diode (OLED, Organic Light-Emitting Diode) display has the characteristics of low power consumption, high resolution, fast response, and bendability, and has become a popular development direction in the display industry. The thinner it is, the more competitive it is in the market. Big. [0005] At present, a thin film transistor (TFT), OLED, and a thin film encapsulation layer (TFE) are sequentially prepared on the flexible substrate. In order to drive the thin film transistor, a driving circuit needs to be bound at the bottom of the flexible substrate to form a display. [0006] However, when the display screen is in operation, the current will generate heat when the current passes through the TFT circuit. In order to facilitate heat dissipation, a heat ...
